4 claims. (ci. 16-129) I This invention relates to an adjustable hinge for heavy doors. v

It is an object of the invention to provide an adjustable hinge for the heavier type of door such as those used on cold storage chambers, refrigerators, vaults and other heavy types ofdoor wherein means will be afforded to permit the easy adjustment of the door within the opening in order for it to properly t the same.

It is another object of the invention to provide an adjustable door hinge which cannot only be adjusted in a horizontal direction but may also be ,adjusted in a vertical direction, and Wherein'the means for elfecting this adjustment is located for easy access thereto and can be effected with a common wrench, and wherein the adjustment can be made without disassembling the hinge.

It is' still another object of the invention to provide a hinge which is adjustable wherein the parts thereof are retain-ed in a precision-like manner with little tolerance so that the parts are truly guided without play.

Otherobjects of the invention are to'provide an adjustable heavy duty hinge which is of simple construction', inexpensive to manufacture, has a minimum number of parts, compact, durable, 'easy to install, easy to adjust, of pleasing appearance, eicient and eiective in use. f

For other `objects and a better understanding of the invention, reference may be had to the v*following detailed description taken in connection withthe accompanying drawing, Yin which: f Figure l is a top plan view of an adjustable' hiuge'con structed according to one form of the' invention;

Fig. 9 is an elevational view of a compartment wall and a door hingedly Yconnected to the `wall by the adjustable hingesconstructcd according to the latter form of the invention. Referring now particularly to Figs; 'l to 4, 1t) represents an adjustable hinge part assembly adapted for connection to a compartment wall and comprising a bottom part l1 having transversely spacedl openings 12'and 12"- through which screws are extended to x the bottom part 11 to the wall. This part 11 has a dovetail groove into which is fitted a block 14 and this extends transversely of the bottom plate 11 and which has a dovetail projection 15 and transversely spaced openings 16 and 17 which are aligned respectively with openings 18 and 19 in the bottom plate 11 and through which attaching bolts are extended to further secure the hinge part assembly 10 the compartment wall.

The block 14 has an opening 21 extending longitudinally -therethrough and through which an adjusting bolt 22 is extended. This bolt 22 has a head 22 and is rotatable in the opening 21. A stop washer 23 is secured to the bolt adjacent the front face of the block to hold the bolt 22 against axial rearward displacement from the block.

A slidable part 25.0f the kassembly 10 is provided with a threaded opening 26 into which the bolt 22l extends so that the slidable part'25, as the bolt 22 is turned, will cause longitudinal adjustment of the part relative to the bottom part 11. This part 25 has a dovetail portion 25 that is slidable in the dovetail groove.

The part 25 has two elongated slots 27 and 27 in order to permit adjustment of the part A25 upon securing bol-ts being passed respectively through openings 2S and 28 in the bottom part 11. After the adjustment has been effected, the bolts, not shown, 'can be tightened so as to hold all parts of the assembly l0 secured to the bottom wall.

The slide par-t 25 hastwo raised hinge bolt receiving portions 29 and 29spaced from one another and between which a Vhinge bolt portion 30 of an elongated hinge part 31 isextended and retained in the hinge-like manner by a hinge pin 32`extending through all Ahinge sleeve portions. -The elongated partf31 has yopenings 32 through which screws are extended'to secure the part 3l to a door.

On ythe forward end of the hinge lslide part 25 is a transverse member 33 that also has a dovetail groove 33 thatreceives the dovetail portion 25 of the slide part 25 and this part 33 is made secure to the slide part by bolts 34 and 35 that extend int-o the threaded openings 36 respectively `on the part 33.

if it is desired to effect an adjustment of the hinge part assembly 10,- the securing bolts that extend through the elongated slots 27 and 27 of the slide part 25 are loosened and the bolt 22 .is turned whereby to cause the longitudinal adjustment of the slide part 25 relative` to the block 14. Since the slidev part 25 has the door fastened thereto through the hinge part 31, the door will beY adjusted as the slide 25 is adjusted. Thereafter, the bolts that may extend through the elongated slots 27 and 27 will be tightened to make a rigid hinge part assembly.

Referring now particularly to Figs. 5 through 9, there will be described a modified form of the invention. According :to this form of the invention, there ys provided a. hinge assembly having a bottom part 41 that is secured to the compartment wall by bolts passing through openings 42 that are countersunk so that the flat heads of the screws will not interfere with the movement of adjustable parts upon the bottom part 41. This part 41 has, at one side thereof, a longitudinally extending dovetail groove or guideway portion 44. longitudinally extending slide part 45 is slidable along the bottom part.41l and is guided by its projection 45 in the Vdovetail groove 44. This slide part V45 has a block raised member 46 Vsecured thereto at Vone side thereof byvits dovetail projection 46 in a dovetailgroove or guideway portion 76 in ,the slide part 45 and vfastening bolts 47 'and`48 to slide therewith. A Vfirst 'o r, outer adjustable screw 49 is journalled inthe raised member 46. This screw has a central threaded opening 50 and a head 49 that lies flush against the side face of the raised member 46. A stop collar Slis secured to the bolt 49 to hold the screw against outward displacement while permitting its rotation in the raised member 46. Since the screw 49 is held against axial displacement, a hinge member 52 into which the screw 49 is threaded can be laterally adjusted across the slide 45 upon set screws 53 and Sd'having been loosened. This hinge member 52 has hinge sleeve portions 55 and 56 spaced from one another and hingeably carries an elongated hinge plate 57 that'is secured between the portions 55 and 56 by its portion 58 and a hinge pin 59; The hinge plate 57 is secured to a door surface by screws entering countersunk openings 64). After the adjustment has been made by turning the outer bolt 49, the transversely adjustable hinge member 52 is made secure to the slide part 45 by tightening the set screws 53 and 54.

In order to effect longitudinal adjustment of the slide part 45 and the hinge member 52, set screws 61 and 62 are loosened from engagement with the bottom of the dovetail longitudinally extending groove 44.' An inner or second adjusting screw 6d is adjustable in the threaded opening Silv of the screw 49. This adjusting screw 64 has a head 64', and its opposite end carries a block 65, Fig. 5, having inclined end faces 65 and 65 that respectively engage with inclined faces of blocks 66 and of the members 66 and 67 so as to adjust the hinge member 52 and the door attached to the hinge member 52 through the hinge part 57 in one direction or the other depending upon the direction in which the adjusting screw 6d is turned. Thereafter, the set screws 53 and 54 will be tightened to hold the hinge member 52 upon lthe slide part 45.

As shown in Fig. 9, two such hinges vare connected to a compartment wall 70 having a door opening 71 in which a door 72 is contained. These hinges are indicated respectively at 73 and 74S. By'turning either of the screws 49 or 64 an adjustment of the hinge parts is effected and the door '72 will be adjusted in the opening 71 to have the proper fitting therein. Thereafter, the set screws will be tightened and the hinge assembly will become a rigid mass.`

For longitudinal adjustment, the inner screw'64 is turned so that the slide part 45 is moved along the keyway 44. For vertical adjustment of the door, the screw 49 is turned so that the hinge member 52 is slid along the slide part 45 with a depending projection '52 of dovetail shape movingjin agroove 76, Figs, 6 and' 8.

lt'should now be apparent that a convenienti means hasbeen provided for adjusting the door 72 in its opening 71 so that there is no need for the door getting out of order and fitting improperly'the'opening'71- shouldv also be apparent that the hinge is formed with a minimum number of parts, all of which are of heavy duty, and adapted to withstandthe load of the heav door 72.
